The APR valve has a bit more tension on the spring and is all metal... With a remap, under the increased intake pressures, the factory plastic Bosch valve can fail or sometimes leak slightly...
I am fairly sure the 911 turbo's run the same DV as the 1.8t so that will give you an indication of the quality of the OEM Bosch item. IMHO there are better ways to spend $200, only replace your DV if it leaks/breaks
